F20-300

Overview

The Triad Magnetics F20-300 is a laminated core power transformer featuring a split bobbin design intended for PCB applications. It operates with a single primary winding rated at 115VAC and dual secondary windings. The unit provides a maximum power rating of 6.0VA. Secondary voltage configurations include parallel connection for 10V at 600mA or series connection for 20V at 300mA. The component utilizes through-hole PC pin termination and offers an isolation voltage of 2500Vrms.

Feature Summary

• Split bobbin construction facilitates flexible printed circuit board mounting and assembly.
• Dual secondary windings allow for configurable voltage outputs in either parallel or series modes.
• Laminated core design supports standard 50Hz and 60Hz line frequency operations.

Applications

• General purpose AC to DC power supply circuits
• Low voltage electronic equipment requiring isolated power
• Industrial control panel instrumentation

Procurement Notes

Verify the specific secondary configuration required for your design, as the part supports both parallel and series connections. Confirm that the 115V primary input matches your system voltage. Ensure the PCB layout accommodates the through-hole pin spacing and physical dimensions of the split bobbin housing. Check RoHS compliance status if environmental regulations apply to your manufacturing process.

Selection Notes

Select this component when a compact, versatile transformer is needed for low-power applications up to 6VA. The split bobbin design is advantageous for reducing parasitic capacitance between windings compared to monolithic cores. Consider the physical size constraints of the PCB, as the laminated core requires adequate clearance. This model is suitable for designs prioritizing flexibility in secondary voltage arrangement over high-frequency performance.

Part Context

The F20-300 belongs to the Split Pack™ series from Triad Magnetics, which specializes in transformers designed for easy integration into printed circuit boards. This series emphasizes versatility through its split bobbin architecture, allowing manufacturers to optimize board space and assembly processes. The F20-300 specifically targets applications requiring reliable isolation and configurable output voltages within a small form factor.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model in the provided documentation. When seeking alternatives, ensure the replacement matches the 6VA power rating, 115V primary input, and compatible secondary voltage/current specifications. Verify that any substitute also features a split bobbin design if PCB mounting flexibility is critical.
